pplication July 29, 1932, Serial No.Y 625,976 2 Claims. (Cl. 299-39) Ourinvention is an upright spray device, commonly called a boom, forspraying trees or other objects and is a combination of assembled pipe,mounted, braced and pivoted in an upright position on a vehicularspraying machine in such a manner thatit carries the spray liquid frompump and pressure tank of the vehicle, through pipes or hoses, or both,to outlets or nozzles arranged to conform to the general contour of 19the tree or object and discharge the spray upon the tree or object,enveloping a complete segment of it with a continuous whirling mist atone time. t

Its advantage over spraying guns and de- 35 vices now4 in use is thefact that it will spray a tree or line of trees with greaterspeed,covering more area at one time than present devices, will reach the topof the tree and the area underneath the low branches and will generateswirls 26 of spray and mist which will reach the underside and allportions of the leaves and branches more efficiently and completely. Theoperation of our device permits a saving of time over the operation ofdevices now used in the trade, in that it can be operated from apropelled vehicle, which carries it through an orchard of trees, alongthe rows, with little or lno halt or delay in the vehicles progress,turning the apparatus toward the tree as it is approached, directly at3G it when opposite and backward toward yit as the tree is being passedand then forward toward the next tree. On turning the vehicle at the endof any tree row being sprayed, in order to direct the spray in the samedirection on the second row it is only necessary to swing the pipe boomon its pivot to the opposite side of i the vehicle and continueuninterrupted without any loss of time. the spraying of fruit trees butits use is not e@ restricted'to fruit trees but may be employed on anytree or object of any kind where spraying is desired. The use of thisdevice is an improvement in the technique of spraying in what each treeis halved and the spray applied over a complete segment at all necessaryangles for thorough coverage. In addition, when spraying with the windthis vcombined mist from all outlets oats more readily through the treecovering much of the other half of the tree 5G from the inside. ITheadvantage ofA such a cornbined fog 'or mist over and through the tree atone time will enable the operator to save material 'and avoid run off ordrip and shorten the time necessary todo the work.

The construction of our device is shown by the It is particularly usefulin,

attached drawings, of which the following are detailed descriptions:

Figure 1 shows a side elevation 'of the device carried upon a spraypumping vehicle.

Figure 2 is an enlarged detail view partly in elevation and partly invertical section'illustrating the mounting of the mast and spray pipe,the .mast being rigid while the spray pipeis capable o f rotation.

Figure 3 is an enlarged section on the line of 3-3 in Figure l. A

Figure 4 is an enlarged section on'the line of 4 4 in Figure 1.

Figure 5 is a plan view looking down from the top of the mast, sprayboom, stays and braces and illustrates the arc in which the pipe orspray boom will pivot. Figure 6 is a detail view in elevation of thelower end of the channel brace beam.

Figure 7 is a view in elevation of the angular channel iron which isadapted to be pivotally supported upon the lower end of the channelbrace beam shown in Figure 6, and forming a support for the auxiliaryspray pipe.

Figure 8 is an enlargement of the end of the lspur pipe with attachednozzle.

In Figure 1, No. 1 represents any Vehicular spray device now .in commonuse, containing tank for storage of spray, pumping apparatus and othermechanical means of forcing the spray into our device.

No. 2 represents a vertical mast which is rigidly fastened upon thevehicle and may be of any appropriate material, height, strength andrigidity and held in place by appropriate braces and stays which, forillustration, we have shown in the drawing, a stay No. 5 and a brace No.6 and No. 7. No. 9 represents the upright pipe which carries lthe liquidspray materials. This' pipe is tted at its base, No. 10, into a pivotseat provided by a metal carrying plate fastened securely on thevehicle, a collar and a socket into'which the pipe fits and turns. ,Thepipe is securely capped at thel bottom to prevent leakage of the sprayliquid and may be strengthened in yits socket by an end section of hardmetal, No. 11, to resist wear, and may, if advisable,- be equipped withball or other suitable bearings to insure ease in pivoting. This uprightpipe, No. 9 is held to the mast by clamps or clevises constructedsubstantially as shown in Figure 4, which is a cross section of themast, No. 2, pipe, No.9, clevis, No. 12 and brace, No. 13. The

clevises are each bolted to an upright channel iron, No. 13, and arefitted into notches in the `of a part of channel iron #15 as drawn.

channel iron. This upright channel 13 is placed between t? e mast. No.pipe, No. 9 as herein lat shown an.

a rigid bearing and hoidiag surface for i tached parts. 1t is in use inthis position in tHe illustration for purposes of rigidity. but we donot limit ourselves to the structure of this or of any other 'of therigidity devices, such as channel iron,No. 15, but they may be of otherconstruction, material or arrangement for securing the bracing andrigidity of pipe arm #14. No. 9, which is the spray boom, is pivoted toturn through substantially the circumference of a circle, and will havea free sweep except as it comes into contact with other parts of themechanism or vehicle. The sweep allowed, however, is suicient forpractical operation and all necessary directions of the spray.

Pipe No. 9 is adjustable and permits the addition of other sections atappropriate places by the usual means of removal of or inserting sections screwed in by ordinary pipe ttings and supplementary bracing. Thepipe No. 9'con tinues as an arm, No. 14, at an angle, to extend andproject above the tops of the trees. At junction of #14 and #9, thejoint can be adjusted by removal of the metal coupling and thesubstitution of a metal coupling of a different angle. No. 15 is achannel iron or other proper support giving rigidity to the pipe,forming fastening points for the outlets, No. 16 holding and carryingthe angled extension pipe at the top and the auxiliary pipe, No. 18 at,the bottom, and of a similar contour as the object to be sprayed. At

the rpoints of contact .between the channel iron,

No,` 15 and the pipe or pipe projections, No. 16 there is a U-boltclamp, No. 17, holding them rigidly together or other suitable means ofrigid attachment.

The portion of the spray pipe shown as No. 18 in Figure l is attached byU-bolts to a channel iron, No. 19 which for sake of convenience is shownas L shaped and these two parts are bolted together flatwise, so thatthey will hinge at point #20 and also fasten at segment arc, #21, togive rigidity and means for discharging the spray at the proper anglesrelative to the tree and also to accommodate the operation ofthe deviceto slope of land or necessary direction of mist from beneath up throughthe branches. The op ation and adjustment of Nos. 15 and 19 is furthershown in Figures 6 and 7. This auxiliary pipe, No. 18 can be swung uponits hinge or pivot, No. 20 to attain any desired vangI of spray, beingheld in the desired position by an arc segment, No. 21 or other devicewith ordinary mechanical fastoning. This arc segment or adjusting devicemay be apart of angular channel iron #19 instead It is l movable whenthe height of the limbs makes its use undesirable. In this case, extraoutlets may be substituted and nozzles added to the upright pipe, inorder to get thorough covering on lower branches.

Pipes Nos.'9 and 18 are attached to the outlet of any ordinary sprayingequipment at any appropriate point by means of flexible hose, No. 22.These pipes and their outlets receive the spray material under pressurefrom any appropriate point of discharge of the spray tank, which iscarried on the vehicle.

shutting oil the ry a similar s .is provided i, may inserted cuffie-.ereat points where it seems advisable to ofi the spray fr outlets of thepipe yond such point.

No. i6 represents spur outlet pipes from the upright main pipe, No. 9and from the auxiliary pipe No. 18, at the points indicated or otherappropriate points, upon the end of each oi which is attached a spraynozzle. No. 25 of usual design and construction. When the spray materialis pumped and the shut ois are all opened, it permits a discharge ofspray simultaneously' over a complete side of the tree which is beingsprayed. It directs the spray downward and up ward as well ashorizontally and at any point-s and in any direction where further spurpipes and nozzles are inserted for complete coverage of the foliage. Theoperation envelopes all leaves and branches on the segment of the heebeing sprayed in a complete fog or inist. T e spur outlet pipes carryingthe nozzles ai .gidiy attached by U-bolts or other suitabie mee-.ns ciattachment to channel iron, No. 13 other rigid brace which may besubstituted. horizontal turn in direction of the whole and spraymechanism is accomplished by s I ing the upright pipe, No. 9 in itspivot by mechanical device suitable for this oper' which may readily becarried forward for ro handling from the drivers seat of the vel'ni Theslack in the hose, No. 22, permits turning while a continuous feed ofspray im rial through them is uninterrupted by the ic motion. y
